Dr. Karletta Chief on Science Fridays

About Science FridayScience Friday is your trusted source for news and entertaining stories about science. Since 1991, host and executive producer Ira Flatow has engaged listeners and scientists with a weekly call-­‐in public radio show. SciFri also produces award-­‐winning digital videos and web content covering everything from octopus camouflage to cooking on Mars. SciFri is brain fun, for curious people.

Science Friday is independently produced by The Science Friday Initiative, a 501(c)(3) nonprofit organization dedicated to science communication and education. The Science Friday radio program is distributed by PRI, Public Radio International. Although we do air on many NPR stations, Science Friday is not an NPR show.

ListeningScience Friday airs live between 2-­‐4 p.m. Eastern Time on public radio stations around the country. Since SciFri is a two-­‐hour-­‐long show, not every station plays both hours. We recommend checking your local station’s listings. Tune in on your local radio, live stream online, or use TuneIn Radio Smart Phone App. If you’re not sure, email Brandon Echter at bechter@sciencefriday.com and he will be happy to check for you. If SciFri doesn’t play in your, your family, or your friend’s area, you can listen to a live stream between 2-­‐4 p.m. Eastern Time at ScienceFriday.com.
